Wut?
360 has halo and gears of war. Thats all. Halo is great il admit that but gears is no uncharted. Ps3 has more exclusives overall which tend to be better.
Games like uncharted 1,2 and 3, MGS4, Ratchet and clank, Most HD remasters are ps3 exclusive, God of war, demons souls, disgaea, killzone, littlebig planet, modnation racers, Resistance, journey, FFversusXIII when its released.
That is just a few of the exclusives on ps3 while xbox only has gears and halo. The rest of its exclusives either suck or were released before ps3 so aren't great since most games aren't at the start of a gen.
